Abstract: The objective of the present invention is to provide a thickener that can increase the viscosity of a composition while suppressing stickiness and maintaining a good feeling when the composition is applied on the skin or the like, since the thickener does not contain a polymer thickener or the amount of the polymer thickener is small. The thickener of the present invention is characterized by comprising a phospholipid and a biosurfactant, wherein a ratio of the phospholipid to 1 part by mass of the biosurfactant is greater than 4:1 and less than or equal to 10:1.

Abstract: The objective of the present invention is to provide a thickener that can increase the viscosity of a composition with suppressing stickiness and maintaining use feeling in the case of applying the composition on the skin or the like, since the thickener does not contain a polymer thickener or the content amount of a polymer thickener is small. The thickener according to the present invention is characterized in comprising a phospholipid, a biosurfactant, and a 1,2-diol compound represented by the following formula (I): HO—CH2—CH(OH)—R1 ??(I) wherein R1 is a hydrocarbon group having a carbon number of 5 or more and 12 or less.

Abstract: Methods are provided for producing a gelatinous composition containing a phospholipid, which has excellent emulsion stability, as well as methods for easily producing an emulsified composition that is excellent in use feeling and emulsion stability. Gelatinous compositions having excellent emulsion stability, and emulsified compositions having excellent use feeling and emulsion stability are also provided. The methods for producing the gelatinous compositions and emulsified compositions comprise dissolving a phospholipid and a cyclic lipopeptide biosurfactant in a polyol solvent or a mixed solvent of water and a polyol to obtain a surfactant solution, and mixing an oily ingredient with the surfactant solution to obtain a gelatinous composition, wherein a mass ratio of the cyclic lipopeptide biosurfactant to the phospholipid in the gelatinous composition is 0.25 or more.

Abstract: A gelatinous composition may include a biosurfactant, water and/or a polyvalent alcohol, an oleaginous component, and an alkaline substance. The alkaline substance may be one or more selected from the group consisting of a hydroxy group-containing amine compound, an alkali metal hydroxide, and a basic amino acid. A concentration of the oleaginous component may be 50 to 99 mass %.

Abstract: A gel-like composition includes a biosurfactant, a polyhydric alcohol, an oily component, and ethanol. The composition may have 0.01 to 10% by weight of the ethanol. The biosurfactant may be one or more selected from the group consisting of surfactin, arthrofactin, iturin, and a salt thereof.

Abstract: A gelatinous composition includes a biosurfactant, at least one of water or a polyol, an oily component, and an unsaturated 7-membered cyclic compound. A content of the unsaturated 7-membered cyclic compound may be 0.01 to 3 wt %, relative to a total weight of the biosurfactant, the at least one of water or a polyol, the oily component and the unsaturated 7-membered cyclic compound. The composition may be in a gelatinous state.

Abstract: An emulsified composition includes an amino-modified silicone oil, an aqueous solvent, and a surfactin. The surfactin is represented by the following formula: where X is an amino acid residue selected from the group consisting of a leucine residue, an isoleucine residue, and a valine residue and R1 is a C9-18 alkyl group.

Abstract: A drainless air conditioner performs an air conditioning process on mixed air, which is a mixture of some indoor air and outdoor air. A first adsorptive heat exchanger and a second adsorptive heat exchanger are capable of performing a humidity conditioning process on the air. An air heat exchanger is capable of exchanging heat between the air and a fluid after it has undergone a heat treatment by a heat source. The outdoor air undergoes a humidity conditioning process by the first adsorptive heat exchanger or the second adsorptive heat exchanger and becomes the mixed together with some of the indoor air. The air heat exchanger exchanges heat between the mixed air and a fluid. Exhaust air undergoes the humidity conditioning process by the first adsorptive heat exchanger or the second adsorptive heat exchanger and is subsequently delivered to the outdoor space.
